Intex Spa Cleaning Kit Maintenance. Maintaining your spa is very important. Floating dirt, such as insects, leaves and other material, is an ideal food source for algae and bacteria. It is therefore necessary to maintain and clean your spa daily. If you do not do this, the water will turn green and the bottom and edge of your spa may become slippery.
